Metabolic syndrome risk factors among a sample of overweight and obese Mexican children.

The objective of this study was to estimate the prevalence and correlations of components of the metabolic syndrome (MetS) using the International Diabetes Federation (IDF) pediatric definition in a cross-sectional study of 215 overweight/obese Mexican children aged 6 to 12. There are no previous studies of this kind in Mexican children. Clinical, anthropometric, and laboratory measurements were performed. The prevalence of MetS using the pediatric IDF criteria was 6.7% (95% confidence interval, 4.0-11.1). A higher proportion of children in the younger age group had waist circumference above the cutoff, while a higher proportion in the older age group had hyperglycemia. Children with MetS had higher percentages of body fat, body mass index, total cholesterol, and low-density lipoprotein cholesterol. Increased triglycerides, decreased high-density lipoprotein cholesterol, and waist circumference were most highly associated with MetS. This has significant implications for public health.
